In 32 games with the Grizzlies, Pill was hitting .341 with nine home runs and 47 RBIs. He also had a 1.054 OPS. Giants manager Bruce Bochy recently offered a hint that Pill would be moving up sooner or later by saying, "He's doing what he has to do."

Pill's recall was timely, since the Giants will begin a two-game Interleague series Tuesday at Toronto. He could be a leading option to fill the designated-hitter role.

During Spring Training, the 28-year-old Pill was hampered in his bid to make the Opening Day roster by a torn meniscus in his right knee that required arthroscopic surgery.

Like Pill, Peguero forced the Giants to recall him on May 3 by hitting .415 in 16 games for Fresno. He hit .188 (3-for-16) in six games with San Francisco, including four starts in left field.
